DETAILED DESCRIPTION

Electric power generation systems (e.g., power generation systems foruse in the oil and gas industry, the industrial power generationindustry, etc.) are known in the art. Components of the prior art powergeneration systems may be mobile (i.e., configured to be transportable),or these prior art power generation systems may be immobile (i.e.,configured to be stationary). The immobile power generation systems maycomprise larger and heavier equipment relative to the mobile systems.Such may, in general, allow the immobile power generation systems togenerate a larger amount of electric power as compared to the mobilesystems. However, the immobile power generation systems cannot berelocated easily, and thus, it is not cost effective to move them to awork site or from one work site to another. In addition, immobile powergeneration systems require significant effort to install, such as byhaving to install concrete, piping, cables, et cetera.

To remedy these issues, mobile power generation systems can be usedinstead (e.g., for an oil and gas and/or industrial power generationapplication). Mobile power generation systems are transportable, can beconfigured for quick installation (relative to immobile power generationsystems), generally do not require significant installation efforts, andrequire minimal installation resources. Typically, the mobile powergeneration systems include one or more trailers that house the powergeneration equipment, and these trailers are set up at the work sitethat requires power. Once the job is completed at that particular worksite, the trailers are packed up and moved to another work site wherepower is required. In this way, the inflexibility of prior art powergeneration systems that are immobile is overcome. However, the prior artmobile power generation systems come with their own set of issues. Forone, the amount of weight that the mobile power generation systems cancarry is limited by the size of the trailers used, the trailer frameand/or suspension, and the towing capability of the vehicles used tomove the trailers. In some instances, more than one trailer may have tobe used to output an amount of electric power equaling that of a typicalimmobile power generation system. Another issue of the mobile powergeneration systems is that they become more complex to assemble as thenumber of trailers increases, and they may require a larger amount ofspace than is available at the worksite.

Each trailer of a multi-trailer power generation system may need to bealigned with its counterparts for operation, which presents its ownissues. This assembly requirement also limits the size, number, and/orconfiguration of the trailers. For instance, locating an electric powergenerator on a first trailer and a gas turbine to drive the generator ona second trailer presents alignment issues that need to be addressed toallow the equipment to function together as desired. Further, increasingthe number of trailers used may increase the complexity and the assemblytime of the system, require an increased area to operate the system,and/or require a larger number of vehicles to transport the system.Thus, while having a plurality of trailers in such systems may provideflexibility, it also introduces significant challenges. In view of thesecompeting considerations, the prior art mobile generation systemstypically limit the number of trailers to two trailers. Embodiments ofthe mobile electric power generation system described herein may employfour trailers but may do so in such a way so as to eliminate or at leastminimize the problems associated with using such a large number oftrailers in a mobile power generation system.

An embodiment 100 of a mobile electric power generation trailer systemis shown in FIG. 1 . The mobile electric power generation trailer system100 (sometimes referred to herein as a “mobile power system”) mayinclude a generator trailer 110, a gas turbine trailer 120, an exhausttrailer 130, and an air filter and ventilation trailer 140. Each of thetrailers 110, 120, 130, and 140 may be completely independent and may beseparately transportable in a transport mode. The trailers 110, 120,130, and 140 may be brought together and easily assembled in anoperational mode to generate power (e.g., generate electrical power forequipment at a work site). The mobile power system 100 may beselectively attached to one or more vehicles 50 (e.g., a truck) (FIG.10A) for transport. For instance, the trailers 110, 120, 130, and 140may each have their own vehicle 50 to enable relocation from one worksite to the next. Alternatively, a single vehicle 50 may transport thetrailers 110, 120, 130, and 140 (e.g., transport one trailer, thentransport another trailer, and so on).

FIG. 2A shows the generator trailer 110 in more detail, and FIG. 2Bshows the generator trailer 110 without its internal components. Thegenerator trailer 110 may have a generator trailer docking plate 111(FIGS. 4A and 4B), a dolly 113, and a generator 114, each mounted to asingle generator trailer frame 112. In embodiments, the generatortrailer 110 may include a separable or detachable jeep 116 with adetachable gooseneck 116 a (e.g., a Schnabel gooseneck). The generator114 may be any suitable number or type of electric power generators nowknown or subsequently developed. The generator 114 may be configured tobe driven by the gas turbine 124 (FIG. 1 ) of the gas turbine trailer120 to produce electricity in the operational mode. The generator 114may benefit from being housed on a separate trailer from the gas turbine124 due to the physical limits imposed on the size and weight oftrailers. That is to say, trailers can only be so big or carry so muchweight before those qualities begin to have a detrimental effect on theoperation of said trailers. Making the trailers too large may result intrailers that are unable to fit and/or effectively maneuver on roadsand/or the work site. Making the trailers too heavy may detrimentallyincrease the likelihood of structural failure. By separating thegenerator 114 from the gas turbine 124, the generator 114 used may havea larger power producing capacity relative to a trailer system whichmust sacrifice capacity to accommodate both a generator and a gasturbine on the same trailer.

The generator trailer frame 112 may be a monocoque truss frame of anysuitable size to fit the components of the generator trailer 110. Theframe 112 may be configured to fit any desirable support equipment (notshown), such as by including an underbelly 112 a for housing the supportequipment. The frame 112 may have wheels or other motive components(e.g., treads) to allow the generator trailer 110 to be moved. The frame112 may also be selectively attachable to the jeep 116 and Schnabelgooseneck 116 a, that in turn may be coupled to a vehicle 50 fortransport during the transport mode. Once the generator trailer 110 hasarrived at the work site, the jeep 116 and the Schnabel gooseneck 116 amay be detached from the generator trailer frame 112 to allow thegenerator trailer 110 to be assembled with the other trailers in theoperational mode. The jeep 116 and the Schnabel gooseneck 116 a, byvirtue of their detachability, may allow the generator trailer 110 to betransportable while having a reduced footprint at the work site once inthe operational mode.

Because the generator trailer frame 112 may be required to supportsignificant weight, the generator trailer 110 may include additionalcomponents such as the dolly 113. The dolly 113 may be an additional setof wheels (e.g., a 6-axle set of wheels) that may reduce the overallload per axle that the generator trailer 110 experiences and increasethe overall stability of the generator trailer 110. By distributing theweight of the generator trailer 110 over a larger number of axles, thegenerator trailer 110 may safely support heavier weights relative to atrailer that utilizes fewer axles. To further aid in the stability ofthe generator trailer 110 when in the transport mode, the jeep 116 mayhave the gooseneck 116 a (e.g., a Schnabel gooseneck). This gooseneck116 a may selectively attach to the generator monocoque frame 112 andprovide stability thereto, which may increase the transportability ofthe generator trailer 110 over various terrain. Once in place at thework site, the Schnabel gooseneck 116 a may be detached from thegenerator trailer 110 along with the jeep 116, and as such, the Schnabelgooseneck 116 a and the jeep 116 may have no impact on the footprint ofthe generator trailer 110 in the operational mode.

Focusing now on FIGS. 3A and 3B, the gas turbine trailer 120 may have amonocoque truss frame 122 (similar in operation to the frame 112) whichmounts the gas turbine 124, a control room 126, air exhaust ports 127,air inlet ports 128, and a gas turbine docking plate 121 (FIGS. 4A and4B). In embodiments, similar to the generator trailer 110, the gasturbine trailer 120 may include an underbelly 122 a for housing supportequipment. Like the generator trailer 110, the gas turbine trailer 120may be a trailer that is movable in the transport mode (e.g., via avehicle 50) and may be assembled with the other trailers 110, 130, and140 at the work site in the operational mode. The gas turbine 124 may beany suitable gas turbine now known or subsequently developed, and thegas turbine 124 may be configured to drive the generator 114. The gasturbine 124 operates by burning fuel (e.g., natural gas) to producemechanical energy (e.g., by turning a shaft), and this mechanical energymay be used to drive the generator 114, which in turn produceselectricity for the work site.

The control room 126 of the gas turbine trailer 120 may include anysuitable control components now known or subsequently developed, asdesired. For instance, in embodiments, the control room 126 may includean auxiliary battery, a motor control center, a lighting anddistribution transformer, and a user control panel. In operation, thecontrol room 126 may be used by a user to monitor, adjust (e.g.,increase/decrease power output), and/or actuate the mobile power system100 in the operational mode. The control room 126 may be configured tocommunicate (e.g., via a wired and/or a wireless connection) with thetrailers 110, 120, 130, 140 of the system 100, and may send and receivedata (e.g., commands, sensor readings, etc.) therebetween.

The gas turbine trailer 120 may have one or more air flow ports thatcorrespond to each of the exhaust trailer 130 and the air filter andventilation trailer 140 when in the operational mode. For instance, thegas turbine trailer 120 may have an exhaust port 127 for moving airbetween the gas turbine trailer 120 and the exhaust trailer 130, andinlet ports 128 a, 128 b, and 128 c for moving air between the gasturbine trailer 120 and the air inlet and ventilation trailer 140. Inembodiments, in the operational mode, the exhaust port 127 and the inletports 128 a, 128 b, 128 c may be on opposing sides of the gas turbinetrailer 120. For example, the exhaust port 127 may be located on theleft (or right) side of the gas turbine trailer 120, and the inlet ports128 a, 128 b, 128 c may be located on the right (or left) side of thegas turbine trailer 120. Having air flow port 127 and air flow ports 128a, 128 b, 128 c on opposing sides of the gas turbine trailer 120 mayenable the exhaust trailer 130 and the air filter and ventilationtrailer 140 (e.g., the port 128 a may correspond to the combustion airsilencer 143 (FIG. 6A), the port 128 b may correspond to the ventilationair supply 144 (FIG. 6A), the port 128 c may correspond to theventilation air discharge 145) (FIG. 6A) to couple to opposing sides ofthe gas turbine trailer 120 in the operational mode (see FIG. 1 ). Suchmay desirably negate the need to cram the exhaust trailer 130 and theair filter and ventilation trailer 140 together on the same side of thegas turbine trailer 120 in the operational mode.

In embodiments, the gas turbine trailer 120 may have a steerable set ofwheels 125 proximate the rear of the trailer 120 (e.g., opposite ofwhere a vehicle 50 may tow the trailer 120). In use, the steerable setof wheels 125 may facilitate aligning of the gas turbine trailer 120with the generator trailer 110 when assembling the trailers 110, 120together in the operational mode. The steerable set of wheels 125 may besteerable, for example, from a pendant.

The generator trailer docking plate 111 and the gas turbine trailerdocking plate 121 are shown in FIG. 4A (where the trailers 110 and 120are separated) and FIG. 4B (where the trailers 110 and 120 are assembledtogether). The generator trailer docking plate 111 and the gas turbinedocking plate 121 may have mating features 111 a and 121 a,respectively. The mating features 111 a, 121 a may be corresponding(e.g., male and female) components that may facilitate mating alignmentof the generator trailer 110 and the gas turbine trailer 120 whenassembling the trailers 110 and 120 in the operational mode. Forexample, the mating features 111 a in the generator trailer dockingplate 111 may be apertures and the mating features 121 a in the gasturbine trailer docking plate 121 may include protrusions, and theapertures 111 a may be sized to receive the protrusions 121 a to couplethe two trailers. In embodiments, the docking plates 111, 121 may beconfigured to receive other securing mechanisms, such as clamps, bolts,screws, et cetera. In use, the docking plates 111, 121 and the matingfeatures 111 a, 121 a may facilitate the alignment of the generatortrailer 110 and the gas turbine trailer 120 during assembly andoperation of the system 100 and ensure the stability of the trailers110, 120 after they are coupled.

Attention is now drawn to FIGS. 5A and 5B, which show the exhausttrailer 130 in the operational mode (FIG. 5A) and the transport mode(FIG. 5B). The exhaust trailer 130 may include a trailer frame 132 andexhaust silencer 133 which mounts a hinged (e.g., horizontally hinged)exhaust inlet 134 and a retractable exhaust outlet 136. In use, theexhaust trailer 130 may be towed (e.g., by a vehicle 50) to a work siteand assembled with the gas turbine trailer 120, where the exhausttrailer 130 may receive and regulate exhaust air from the gas turbinetrailer 120. The exhaust trailer 130 may, in embodiments, serve to keepthe noise from the gas turbine trailer 120 within regulatory (e.g.,environmental) standards.

The hinged exhaust inlet 134 may be configured to couple to the gasturbine trailer 120 (e.g., to the exhaust air port 127 thereof) and mayreceive therefrom the gas turbine 124 exhaust air. The hinged exhaustinlet 134 may be selectively switchable between two positions. The firstposition may be a position where the hinged exhaust inlet 134 is coupledto an exhaust air plenum 135 a of the exhaust trailer 130 such that thegas turbine 124 exhaust air may be directed through the hinged exhaustinlet 134 and into the plenum 135 a. Typically, the hinged exhaust inlet134 may be put into the first position when the system 100 is beingassembled into the operational mode. The second, or storage, positionmay be a position where the hinged exhaust inlet 134 is not operablycoupled to the plenum 135 a, such that hinged exhaust inlet 134 nolonger directs air into the plenum 135 a. In the second position, whichis typically used for the transport mode of the system 100, the hingedexhaust inlet 134 may be arranged in a manner that facilitates transportof the exhaust trailer 130. For example, in an embodiment and as shownin FIG. 5B, the hinged exhaust inlet 134 may be moved in a horizontalplane from the first position to lie generally parallel to the exhausttrailer frame 132, behind the plenum 135 a. In other embodiments, thehinged exhaust inlet 134 may be moved in other directions (e.g.,vertically, axially, etc.) to be put into the second position. In thisway, the hinged exhaust inlet 134 may be secured in a storage positionand precluded from unduly interfering in the transport of the exhausttrailer 130.

The retractable exhaust outlet 136 may receive exhaust air from a plenum135 b (which may itself be operably coupled to air plenum 135 a) andrelease the exhaust air into the ambient (e.g., environmental) air. Theretractable exhaust outlet 136 may be selectively movable between afirst position and a second position. The first position, which istypically used when the system 100 is in the operational mode, may bewhere the retractable exhaust outlet 136 is extended such that theretractable exhaust outlet 136 may facilitate the transition of theexhaust air from the plenum 135 b to the outside ambient air. The secondposition, which is typically used when the system 100 is in thetransport mode, may be where the retractable exhaust outlet is retractedwithin the exhaust trailer 130 (e.g., the plenum 135 b) and/or afootprint thereof. In this second position, the retractable exhaustoutlet may be precluded from unduly interfering with the transport ofthe exhaust trailer 130.

To facilitate the transition between the first and second positionsdescribed above, one or more of the hinged exhaust inlet 134 and theretractable exhaust outlet 136 may include an actuator 137. Theactuators 137 may include, for example, one or more hydraulic (orpneumatic, motorized, etc.) devices that facilitate the transition ofthe components 134 and/or 136 between their two positions. Inembodiments, the hinged exhaust inlet 134 and/or the retractable exhaustoutlet 136 may alternatively or additionally be configured to betransitioned between the two positions by hand.

Focus is now directed to FIGS. 6A and 6B, which illustrate the airfilter and ventilation trailer 140. The air filter and ventilationtrailer 140 may include a trailer frame 142 which mounts an air intakefilter 141, a combustion air silencer 143, a ventilation air supply 144,a ventilation air discharge 145, and an anti-icing system 146. In use,the air filter and ventilation trailer 140 may provide both combustionair to the gas turbine 124 and ventilation air to the gas turbinetrailer 120. The air filter and ventilation trailer 140 may beselectively switchable between the operational mode, where the trailer140 is assembled with the gas turbine trailer 120 and provides airthereto, and a transport mode, where the trailer 140 is configured to bemovable (e.g., by a vehicle 50).

The air intake 141 may be any suitable device now know or subsequentlydeveloped that is configured to intake ambient, or other, air. Thisambient air may then be routed through the combustion air silencer 143to the gas turbine 124 where the ambient air may be used to facilitatethe combustion of the fuel therein. In some embodiments, the combustionair intake 141 may also filter the ambient air such that the ambient airis made more suitable to be used by the gas turbine 124. In addition,the combustion air silencer 143 may serve to keep the noise from the gasturbine 124 within regulatory standards.

Like the combustion air silencer 143, the ventilation air supply 144 maymake use of ambient air provided by the air intake filter 141. However,the ventilation air supply 144 may instead route the ambient air intothe gas turbine trailer 120 itself. With the aid of the ventilation airdischarge 145 (which itself may direct air out from the inside of thegas turbine trailer 120), the air within the gas turbine trailer 120 maybe circulated, such as for the purposes of temperature control, ensuringsafe breathing air, et cetera. The air removed from the gas turbinetrailer 120 may, in embodiments, be vented to atmosphere.

The anti-icing system 146, as seen in FIG. 6B, may include a ventilationdischarge plenum 147, a blower 148, and one or more warming devices 149.The ventilation discharge plenum 147 may collect some or all of the airdirected by the ventilation air discharge 145, and route the collectedair to the blower 148. The blower 148 may be any suitable blower fan nowknown or subsequently developed, and may redirect the air collected inthe ventilation discharge plenum 147 through the warming devices 149.The warming devices 149 may be adjacent the air intake 141, and maytransport the redirected air across (e.g., vertically, horizontally,diagonally, in a pattern, etc.) the air intake 141. In some embodiments,the warming devices 149 may be configured (e.g., via apertures) toinject the redirected air in and/or on the air intake 141 itself. Inoperation, the anti-icing system 146 may collect the ventilation airwarmed inside the gas turbine trailer 120 and direct the warmedventilation air to the air intake 141 to provide a warming effectthereto. This warming of the air intake 141 may offset some or all ofthe detrimental effect of below optimal ambient temperatures the airintake 141 may be experiencing, such as by melting ice that may haveformed on the air intake 141 during cold temperature operation. Inembodiments, the warmed air provided by the anti-icing system 146 mayalternatively or additionally serve to warm the ambient air being takenin by the air intake 141, which may augment the capabilities (e.g., theefficiency and/or the total power output) of the gas turbine 124. Theartisan would understand that the anti-icing system 146 itself and/orthe operation thereof may be optional in embodiments configured for usein warmer climates, where cold ambient air may not be as much of aconcern.

In the operational mode, each of the combustion air silencer 143, theventilation air supply 144, and the ventilation air discharge 145 may becoupled to the corresponding air intake ports 128 a, 128 b, 128 cprovided on the gas turbine trailer 120. For instance, in theoperational mode, the combustion air silencer 143 may be operablycoupled to the port 128 a, the ventilation air supply 144 may beoperably coupled to the port 128 b, and the ventilation air discharge145 may be operably coupled to the port 128 c. In the transport mode,each of the combustion air silencer 143, the ventilation air supply 144,and the ventilation air discharge 145 may be retracted within the airfilter and ventilation trailer 140 and/or a footprint thereof topreclude the components 143, 144, or 145 from unduly interfering withthe transport of the trailer 140. In embodiments, one or more actuators(as described above with respect to actuators 137) may be used tofacilitate the movement of the components 143, 144, and 145.

Attention is now directed to FIGS. 7A and 7B, where a stabilization (or“lift”) system 150 for stabilizing one or more of the trailers 110, 120,130 and/or 140 in the operational mode is shown. While the stabilizationsystem 150 is shown here in use with the trailer 120, the artisan wouldunderstand that the stabilization system 150 may be used with any or allof the trailers of the mobile power system 100. The stabilization system150 may include one or more restraints 152. The restraints 152 maypreclude the trailer from undesirably tipping or moving, such as duringhigh wind conditions or seismic activity. For example, the restraints152 themselves may provide additional stability to their respectivetrailer, and/or may be configured to be secured to a surface (e.g., aconcrete pad) to provide extra stability. In some embodiments, thestabilizer system 150 may alternatively or additionally provide dampingto the trailers, such that harmful forces (e.g., large vibrationalforces) acting thereupon are mitigated or otherwise attenuated. Whentransitioning to the transport mode, the restraints 152 may be decoupledfrom the trailers.

Referring to FIG. 7B, the same structure that is included on trailer 120to connect the restraints 152 may be used to alternatively oradditionally connect lift bars 154. The lift bars 154 may be used tolift the trailer (e.g., the entire trailer). Similar to the restraints152, the lift bars 154 may be decoupled from the trailers 110, 120, 130,and/or 140 when transitioning to the transport mode.

Focus is now directed to FIGS. 8A-8F, where a trailer slide system 160is shown. Each of the trailers (e.g., trailers 110, 120, 130, 140) ofthe mobile power system 100 may have a trailer slide system 160, thoughin embodiments, one or more of the trailers may forego the trailer slidesystem 160. The trailer slide system 160 may include one or moremounting bars 162, supports 164, and actuators 166. In operation, thetrailer slide system 160 may facilitate the repositioning of thetrailers of the system 100 when in the operational mode. In other words,the trailer slide system 160 may be able to minutely adjust and/or alignthe trailers 110, 120, 130, and/or 140 when assembling them into theoperational mode. Properly aligning the trailers may be important toensure that certain components, such as the air ports 127, 128 a, 128 b,128 c, are able to properly interface with their corresponding trailers(e.g., trailers 130 and 140, respectively).

The adjustments to the position of the trailers made by the trailerslide system 160 may be small (e.g., up to two feet in each direction)relative to the size of the trailers. However, the trailer slide system160 may facilitate repositioning of the trailers when in the operationalmode, where the trailers may otherwise be unable to move (e.g., becausethey are decoupled from their vehicles 50). With prior art mobile powergeneration systems, coupling, decoupling, and repositioning withvehicles to ensure the prior art trailers properly attach to each otheris often a time-consuming task, particularly because operational spacein the work site is limited. Thus, even a small misalignment ormisplacement of the prior art trailers upon initial placement may resultin costly delays spent on repositioning the prior art trailers, andequipment failure may occur if misaligned equipment is used. Therefore,there is a need for a way to reposition trailers of a mobile powersystem quickly and efficiently. The trailer slide system 160 and itsembodiments disclosed herein may provide for such.

The one or more mounting bars 162 may be slidably mounted to the frameof a trailer (e.g., trailer 110, 120, 130, and/or 140), and eachmounting bar 162 may include a plurality of supports 164 (e.g., locatedon opposing side of the frame) and a plurality of actuators 166. Each ofthe plurality of supports 164 may have a foot 164 a which is movable(e.g., vertically) to bring the trailer slide system 160 into contactwith the ground to give a surface for the trailer slide system 160 topush off. The mounting bars 162 and/or the supports 164 may be operablycoupled to actuators 166 (e.g., hydraulic cylinders and/or arms), whichmay provide motion to the mounting bars 162 and/or the supports 164. Inturn, this movement of the mounting bars 162 and the supports 164 mayprovide overall motion to the trailer frame itself. In embodiments, theactuators 166 may be able to move the supports 164 and the mounting bars162 in both a lateral direction (FIGS. 8B-8D) and a longitudinaldirection (FIGS. 8E-8F).

Example operation of the trailer slide system 160 is described below,with reference to FIGS. 8A-8F. In FIG. 8B, the feet 164 a (FIG. 8A) ofthe supports 164 are lifted off the ground. Then, the mounting bars 162are slid to the right of the trailer (up on the page) using theactuators 166, as seen in FIG. 8C. Next, in FIG. 8D, the feet 164 a areplaced on the ground and the mounting bars 162 are slid to the left(down on the page), causing the entire trailer to move to the right (upon the page). Next, in FIG. 8E, the feet 164 a are once more lifted fromthe ground, and the mounting bars 162 are slid to the rear of thetrailer (right on the page). Finally, in FIG. 8F, the feet 164 a areplaced on the ground once more and the mounting bars 162 are slide tofront of the trailer (left on the page), causing the entire trailer tomove back (to the right of the page). The artisan would understand theabove-described operation and the associated figures are merelyexemplary and are not meant to be limiting. For example, the trailerslide system 160 may be used to adjust the trailer forward, back, left,and/or right as desired.

Using the trailer slide system 160, the trailers 110, 120, 130, and 140may quickly and efficiently assemble and/or align in the operationalmode. The vehicles 50 may place the trailers 110, 120, 130, and 140 intheir approximate location, and then the trailer slide system 160 may beused to correct any errors in position such that the trailers 110, 120,130, and 140 may be aligned and coupled to each other. The trailer slidesystem 160 may be controlled, for example, by a control panel (notshown) mounted to the trailer frame that the trailer slide system 160resides on.

FIG. 9 is a flowchart illustrating a method 700 of operating the variousembodiments of the mobile power system disclosed herein. FIGS. 10A-10Fpictorially depict the steps of the method 700, in an embodiment (i.e.,FIG. 10A depicts step 702, FIG. 10B depicts step 704, FIG. 10C depictsstep 706, FIG. 10D depicts step 708, FIG. 10E depicts step 710, and FIG.10F depicts steps 712 and 714). The method 700 may be used to transitionthe trailers 110, 120, 130, and 140 from the transport mode to theoperational mode, where the system 100 may generate power at a worksite. First, at step 702, the system 100 may start in the transport modewhere each of the trailers 110, 120, 130, and 140 are separate andindependently movable with vehicles 50. The generator trailer 110 isthen moved onto (e.g., backed into) the work site. Then, at step 704,the jeep 116 and the Schnabel gooseneck 116 a are detached, along withthe vehicle 50, leaving behind the generator trailer 110. Next, at step706, the gas turbine trailer 120 is brought by a vehicle 50 and brought(e.g., backed into) into contact, or close proximity, with the generatortrailer 110. Then, at step 708, the vehicle 50 may detach from the gasturbine trailer 120 and leave. At step 710, the generator trailer 110and the gas turbine trailer 120 may be coupled together. For example,the trailers 110, 120 may utilize their respective trailer slide system160 to bring the trailers 110, 120 in alignment, and then the dockingplates 111, 121 may be mated to complete the coupling. Here, thestabilizers 150 may be set up to provide extra stability to the trailers110, 120.

The method 700 is continued on FIG. 10F, where at step 712, the exhausttrailer 130 is moved (e.g., pulled forward) onto the work site anddetached from its vehicle 50. Here, the trailer slide system 160 of theexhaust trailer 130 may be used to bring the exhaust trailer 130 inalignment with the gas turbine trailer 120. The exhaust trailer 130 maybe operably coupled to the exhaust air port 127 of the gas turbinetrailer 120. In embodiments, the stabilizer 150 of the exhaust trailer130 may be set up. Step 714 may essentially repeat the process of step712, except now using the air filter and ventilation trailer 140, wherethe trailer 140 is brought on site and operably coupled to the air inletports 128 a, 128 b, 128 c of the gas turbine trailer 120. The artisanwould understand that the order of the steps 712 and 714 may beinterchangeable (i.e., the air filter and ventilation trailer 140 may becoupled to the gas turbine trailer 120 before the exhaust trailer 130).

The steps of the method 700 may be omitted, added to, or modified toimplement the various embodiments of the mobile power system describedherein. For example, to move the system 100 from the operational mode tothe transport mode, the steps of the method 700 may essentially beperformed in reverse. As another example, the step of setting up thestabilizing systems 150 may be omitted. As yet another example, themethod 700 may be modified to include one or more steps of aligning oneor more of the trailers 11, 120, 130, and/or 140 using a trailer slidesystem (e.g., the trailer slide system 160 or the trailer slide system160′ described below).

Focus is now directed to FIGS. 11A-13D, where a trailer slide system160′ (sometimes referred to herein as a “trailer alignment system”) isshown. The trailer slide system 160′ may be substantially the same orsimilar to the trailer slide system 160, except where expressly noted orinherently implied. Each of the trailers (e.g., trailers 110, 120, 130,140) of the mobile power system 100 may have a trailer slide system160′, though in embodiments, one or more of the trailers may forego thetrailer slide system 160′. The trailer slide system 160′ may include oneor more outer mounting bars 161′, one or more inner mounting bars 162′,hydraulic cylinders 163′ and 166′, hydraulic legs 164′, and one or moremounting bar tie-bars 165′. In operation, the trailer slide system 160′may facilitate the repositioning of the trailers of the system 100 whenin the operational mode. In other words, the trailer slide system 160′may be able to minutely adjust and/or align the trailers 110, 120, 130,and/or 140 when assembling them into the operational mode. Properlyaligning the trailers may be important to ensure that certaincomponents, such as the air ports 127, 128 a, 128 b, 128 c, are able toproperly interface with their corresponding trailers (e.g., trailers 130and 140, respectively). In embodiments, the trailer slide system 160′may adjust the trailers of the system 100 up to six inches in each ofthe side-to-side directions (i.e., laterally) and up to six inches ineach of the backwards and forwards directions (i.e., longitudinally).

The adjustments to the position of the trailers made by the trailerslide system 160′ may be small relative to the size of the trailers.However, the trailer slide system 160′ may facilitate repositioning ofthe trailers when in the operational mode, where the trailers mayotherwise be unable to move (e.g., because they are decoupled from theirvehicles 50). With prior art mobile power generation systems, coupling,decoupling, and repositioning with vehicles to ensure the prior arttrailers properly attach to each other is often a time-consuming task,particularly because operational space in the work site is limited.Thus, even a small misalignment or misplacement of the prior arttrailers upon initial placement may result in costly delays spent onrepositioning the prior art trailers, and equipment failure may occur ifmisaligned equipment is used. Therefore, there is a need for a way toreposition trailers of a mobile power system quickly and efficiently.The trailer slide system 160′ and its embodiments disclosed herein mayprovide for such.

Each of the outer mounting bars 161′, as best shown in FIGS. 11A-12D,may have retained therein an inner mounting bar 162′ such that the innermounting bar 161′ is slidable relative to the outer mounting bar 161′and/or whichever frame of the trailer (e.g., trailer 110, 120, 130,and/or 140) the outer mounting bar 161′ is fixed to. That is to say, oneend of the inner mounting bar 162′ may displace (e.g., extend or retractsome distance) inside the outer mounting bar 161′, and the opposing endof the inner mounting bar 162′ may correspondingly displace the samedistance. Each end of the inner mounting bar 162′ may have an actuated(e.g., hydraulicly actuated) leg 164′. These legs 164′ may be capable ofbringing one or more feet of the trailer slide system 160′ in contactwith a ground surface. By pressing the feet into the ground surface, thetrailer slide system may stabilize the trailer system 100. The legs 164′may be configured to lift the trailer attached thereto off the ground ina manner that makes the trailer capable of movement relevant to theground.

Similar to the actuators 166, the trailer slide system 160′ may have oneor more actuators 163′ (e.g., hydraulic cylinders) to provide movementto the inner mounting bar 162′. For example, an actuator 163′ may belocated within the outer mounting bar 161′ and/or the inner mounting bar162′ such that the actuator 163′ may readily move the inner mounting bar161′ laterally relative to the trailer frame. As best shown in the topview of FIG. 11B and the detailed views of FIGS. 11C and 11D, each setof mounting bars 161′ and 162′ may have one actuator 163′ that is biasedto one side of the trailer frame, in embodiments. The actuator 163′ maybe configured to move a distance in both directions, for example, sixinches both left and right. In turn, this movement of the actuators 163′may provide overall motion to the trailer frame itself.

Example operation of the trailer slide system 160′ in the lateraldirection is described below, with reference to FIGS. 12A-12D. In FIG.12A, the inner mounting bar 161′ is slid to the right of the trailer(right and up on the page) using the actuator 163′, to end in theposition seen in FIG. 12B. The final position of the inner mounting bar161′ movements is visualized in FIG. 12D. The leg 164′ is used toraise/lower (FIG. 12C) the trailer slide system 160′ and bring it incontact with the ground during this process to provide overall motion tothe trailer relative to the ground.

The artisan would understand that the inner mounting bar 161′ may bepreemptively set to one side of center before the legs 164′ aredeployed, so that when the legs 164′ are deployed, the trailer slidesystem 160′ may move the trailer frame a greater distance in a directionthan if the inner mounting bar 161′ was centered. To illustrate anexample, say the inner mounting bar 161′ is moved to its leftmost extent(e.g., six inches left from center) before the legs 164′ are deployed.The trailer frame would not move relative to the ground at this point.Then, the legs 164′ are brought into contact with the ground, and theinner mounting bar 161′ is now moved to its rightmost extent (e.g., sixinches right from center). With the legs 164′ deployed, the trailerframe would now move the full twelve inches to the right. In thismanner, the trailer slide system 160′ may move the trailer frame alarger distance in a direction than if the inner mounting bar 161′ wascentered.

Focusing now on FIGS. 13A-13D, actuators 166′ (which may besubstantially the same or similar to the actuators 163′) and tie bars165′ may work to provide movement to the trailer slide system 160′ andthe trailer frame in the longitudinal direction. The one or more tiebars 163′ may be coupled to opposing outer mounting bars 161′ and/orinner mounting bars 162′ such that, when acted upon by the actuators166′, the tie bars 165′ may displace the trailer slide system in thelongitudinal direction. The tie bars 165′ may couple opposing mountingbars 161′ and/or 162′ such that the opposing mounting bars 161′, 162′remain a fixed distance from each other in the longitudinal direction.The actuators 166′ may be configured to move a distance in bothdirections, for example, six inches both forward and backward. In turn,this movement of the actuators 166′ may provide overall motion to thetrailer frame itself.

Example operation of the trailer slide system 160′ in the longitudinaldirection is described below, with reference to FIGS. 13A-13D. In FIG.13A, the inner mounting bar 161′ and the outer mounting bar 161′ areslid to the back of the trailer (right and up on the page) using theactuator 166′, to end in the position seen in FIG. 13B. The leg 164′ isused to raise/lower (FIG. 3C) the trailer slide system 160′, asdescribed above, and bring it in contact with the ground during thisprocess to provide overall motion to the trailer relative to the ground.

The artisan would understand that the inner mounting bar 161′ and theouter mounting bar 162′ may be preemptively set to one side of centerbefore the legs 164′ are deployed, so that when the legs 164′ aredeployed, the trailer slide system 160′ may move the trailer frame agreater distance in a direction than if the inner mounting bar 161′ andthe outer mounting bar 162′ were centered. To illustrate an example, saythe inner mounting bar 161′ and the outer mounting bar 162′ are moved totheir rearmost extent (e.g., six inches rearward from center) (FIG. 13B)before the legs 164′ are deployed. The trailer frame would not moverelative to the ground at this point. Then, the legs 164′ are broughtinto contact with the ground, and the inner mounting bar 161′ and theouter mounting bar 162′ are now moved to their forwardmost extent (e.g.,six inches forward from center) (FIG. 13D). With the legs 164′ deployed,the trailer frame would now move the full twelve inches forward. In thismanner, the trailer slide system 160′ may move the trailer frame alarger distance in a direction than if the inner mounting bar 161′ andthe outer mounting bar 162′ were centered.

The artisan would understand the above-described operation and theassociated figures are merely exemplary and are not meant to belimiting. For example, the trailer slide system 160′ may be used toadjust the trailer forward, back, left, and/or right as desired atgreater or lesser distances described above (i.e., in embodiments whichmay move at distances more or less than six inches in each direction).

Using the trailer slide system 160′, the trailers 110, 120, 130, and 140may quickly and efficiently assemble and/or align in the operationalmode. The vehicles 50 may place the trailers 110, 120, 130, and 140 intheir approximate location, and then the trailer slide system 160′ maybe used to correct any errors in position such that the trailers 110,120, 130, and 140 may be aligned and coupled to each other. The trailerslide system 160′ may be controlled, for example, by a control panel(not shown) mounted to the trailer frame that the trailer slide system160′ resides on.

Because locating the generator and the gas turbine components onseparate trailers may increase the difficulty of suitably producingelectricity (e.g., due to the added complexity and/or the risk of partmisalignment), prior art discourages and teaches away from mobile powergeneration systems having separate trailers for the generator and thegas turbine. The prior art likewise discourages use of separate trailersfor the air inlet and the exhaust. However, with the docking plates 111,121, the mating features 111 a, 121 a, and the trailer slide system 160,the system 100 may reap the benefits of employing a plurality oftrailers while eliminating or at least minimizing the typical downsidesof so doing. For example, the trailer slide system 160 may address someof the difficulties of assembling a plurality of trailers by allowingthe trailers of the system 100 to be repositioned after being decoupledfrom their respective towing vehicles.

While the embodiments described herein typically rely on an externalvehicle 50 to tow the trailers 110, 120, 130, and 140, embodiments wherethe mobile power system 100 uses alternative methods to enable thetrailers 110, 120, 130, and 140 to relocate are also contemplated. Forexample, in embodiments, two or more trailers may be integrated fortransport. In a currently preferred embodiment, however, each trailer110, 120, 130, and 140 is independently transportable and the trailers110, 120 are not configured to be transported once they are assembledtogether for operation.

The artisan will understand that the mobile power system 100 disclosedherein may include or have associated therewith electronics (e.g.,within the control room 126). The electronics may be used to control andmodify the operation of the mobile power system (e.g., controloperations of the gas turbine and the generator, monitor operations ofthe gas turbine and the generator, et cetera). In some exampleembodiments, the processor or processors may be configured throughparticularly configured hardware, such as an application specificintegrated circuit (ASIC), field-programmable gate array (FPGA), etc.,and/or through execution of software to allow the mobile power system100 to function in accordance with the disclosure herein.

While example applications (e.g., suppling electricity to hydrocarbonextraction sites and/or industrial power generation projects) are usedto illustrate the workings of the system 100, the artisan willunderstand that the mobile power system 100 disclosed herein may beadapted to other mobile applications, and that such adaptions are withinthe scope of the present disclosure. Examples of other mobile powersupply applications may include any application where a supply ofelectricity is needed, such as a temporary base of operations for aworkforce, a large social gathering, et cetera. Examples of non-powerrelated applications where aspects of the disclosure may be employedinclude, e.g., use of the trailer slide system in other applicationswhere speedy, minute positional adjustment of trailers is beneficial.

Thus, as has been described, the mobile electric power generationtrailer system concepts disclosed herein may serve to minimize theeffect of using multiple trailers to generate power, and in so doing,provide a mobile power system that is relatively time-efficient and easyto operate. Moreover, the trailers using the trailer slide systemconcepts disclosed herein may significantly reduce the chance for anequipment misalignment to occur, thus preserving expensive operatingequipment, as described above in other embodiments.

Many different arrangements of the various components depicted, as wellas components not shown, are possible without departing from the spiritand scope of the present disclosure. Embodiments of the presentdisclosure have been described with the intent to be illustrative ratherthan restrictive. Alternative embodiments will become apparent to thoseskilled in the art that do not depart from its scope. A skilled artisanmay develop alternative means of implementing the aforementionedimprovements without departing from the scope of the present disclosure.It will be understood that certain features and subcombinations are ofutility and may be employed without reference to other features andsubcombinations. Not all steps listed in the various figures need becarried out in the specific order described.
